# Electricity - Static Electricity

Electricity is a major topic covered in GCSE Physics. One aspect of electricity that students will learn about is static electricity - a stationary electric charge produced by the transfer of electrons between certain insulators as a result of friction. In this quiz we look at some examples of static electricity and at some of its effects.

Have you ever been 'zapped' as you get out of a car or touched metal shelving in a shop with carpeting on the floor? Have you ever rubbed a balloon on your clothing and stuck it to a wall? Have you ever watched lighning during a storm? If you have, then you have experienced static electricity in action!

Static electricity is a stationary electric charge, produced by friction acting on certain electrical insulators. As you rub an insulator, such as the soles of your shoes on the carpet or the balloon on your clothing, electrons are knocked off some of the atoms and are transferred from one to the other.

1.
If one positively charged material and one negatively charged material are brought in close proximity to one another, what force do they exert on each other?
Strong nuclear
Magnetic
Repulsive
Attractive
Two materials which have different types of electrical charge will always attract one another
2.
Which material from the list below allows an electrical current to pass through it easily?
Brass
Polystyrene
Card
Porcelain
Metals allow electrical currents to pass through them easily due to the high number of free electrons within the material
3.
If two polystyrene rods are rubbed with a duster and gain electrons, how will the rods react to one another when they are brought close together?
Repel
Attract
Merge into a super rod
Melt
They both gain electrons so must be negatively charged - two objects with the same electrosatatic charge will repel each other
4.
What type of charge does the material gaining electrons have?
Positive
Negative
No charge
Both positive and negative
A material that gains electrons will always become negatively charged as the electrons themselves are negatively charged
5.
If two charged materials are brought close together, what do they exert on each other?
A force
Ultra sonic waves
Heat
We talk of this as being an electrostatic force
6.
If two positively charged materials are brought in close proximity to one another, what force do they exert on each other?
Attractive
Repulsive
Strong nuclear
Magnetic
Repulsion works with positive charges the same as it does with negative charges
7.
If two negatively charged materials are brought in close proximity to one another, what force do they exert on each other?
Attractive
Repulsive
Strong nuclear
Magnetic
Charges of the same type repel
8.
What is 'rubbed' off one material and onto the other?
Neutrons
Protons
Electrons
Dirt
These collect on the surface of the negatively charged object
9.
What type of charge does the material losing electrons have?
Positive
Negative
No charge
Both positive and negative
Since the object was electrically neutral beforehand, losing negative charge will mean that it ends up with a positive charge
10.
What do certain insulating materials become when they are rubbed against each other?
Electrically charged
Friends
Electrically neutral
Nothing
One becomes positively charged and the other becomes negatively charged by the same amount
